玉米是我省的主要秋粮作物,种植面积较大。近年来农民为了腾茬种麦,过早就掰棒收获,不但造成减产,而且也降低了品质。经我校调查,农民一般在玉米有60%的枯黄叶时掰棒,比成熟期(100%叶片枯黄)收获减产12~15%。带秤收获具有以下好处。 1、降低减产幅度 玉米带秆收获,集中直立堆放,自然后熟,比成熟期收获的玉米只减产4~7%。 2、缩短生育时期 玉米带秆收获,可缩短玉米在田间生长期7~10天,能早腾茬,适时种麦,有利于小
Corn is the main autumn crop in our province, with a larger planting area. In recent years, farmers in order to stubble crop wheat, early breaking rod harvest, not only resulted in reduced production, but also reduced the quality. As surveyed by our school, peasants generally break off sticks when they have 60% of yellowish corn leaves and 12% to 15% more than the mature ones (100% leaves are yellowish). Balanced harvesting has the following benefits. 1, reduce the yield reduction Maize stalk harvest, concentrated upright pile, natural ripe, than the mature harvest of corn only 4 to 7% reduction. 2, shorten the growth period of maize stalk harvest, can shorten the corn growth stage in the field 7 to 10 days, early stubble, timely wheat, is conducive to small
